The original
KoboldCpp
A single executable that runs GGUF language models locally, with a web interface and no installation at all.
Replacements
Listings that take over the same core job as KoboldCpp.
llama.cpp
The C++ engine most local AI apps are built on, running language models on ordinary hardware.
llama.cpp is the MIT-licensed C++ engine with a built-in server and basic web interface, offering many GPU backends but focused on text rather than bundled image and speech.
Ollama
The simplest way to pull down an open language model and run it on your own machine, from one command or a desktop app.
Ollama pulls and runs models with one command and a localhost REST API under MIT, handling model downloads for you rather than requiring manual file hunting.
LM Studio
A polished desktop app for downloading, running and chatting with local language models, with an OpenAI-compatible server built in.
LM Studio gives a polished desktop interface with Hugging Face model search and an OpenAI-compatible server, but it is closed source rather than AGPL-licensed.
llamafile
Packages a language model and the code to run it into one executable file that works on several operating systems without installation.
llamafile packages the model and runtime into one Apache-licensed executable that runs across operating systems, though files get large and Windows has a size limit.
TextGen
Chat with local language models using the TextGen desktop interface.
TextGen is another AGPL-3.0 local interface with text, vision and API access in portable builds, offered as a desktop interface rather than a single executable.
LocalAI
Serve language, image and speech models on your own hardware.
LocalAI serves language, image and speech models through compatible APIs under MIT, but it is listed for Linux, macOS and self-hosting rather than Windows.
Jan
An open-source ChatGPT replacement that runs entirely offline, and can also front cloud providers when you want them.
Jan offers an Apache-licensed offline chat app with installers and cloud provider support, trading KoboldCpp's image and speech features for a simpler chat interface.
GPT4All
A local AI chat app with document chat built in, from Nomic AI. Stable, MIT licensed, but not updated since early 2025.
GPT4All is an MIT-licensed local chat app with LocalDocs document chat and CPU operation, but it has not been updated since February 2025.
Also worth comparing
These listings name KoboldCpp as their own alternative, so the relationship runs both ways.
SillyTavern
A locally-installed front end for language models aimed at long-form roleplay and character-driven writing.
KoboldCpp is a single AGPL-3.0 executable that runs GGUF models with its own web interface, so no separate backend is needed, though the interface is dense.
vLLM
High-throughput, memory-efficient inference and serving engine for LLMs.
KoboldCpp is a single AGPL-3.0 executable that runs GGUF models on CPU or GPU and exposes OpenAI and Ollama compatible endpoints, needing no installation.
Similar software
Related functionality, not a direct replacement.
Open WebUI
A self-hosted chat interface that talks to Ollama and any OpenAI-compatible API, so your local models get a proper front end.
ComfyUI
Construct AI generation workflows with a visual node graph.
Whisper
An open-source speech recognition model from OpenAI for transcribing and translating audio on your own machine.
Chatbox
A desktop and mobile chat client for AI models, where you supply your own API keys or point it at a local model.
